Background summary
Overactive Bladder can result from neurological disease such as in patients
with spinal cord injury or multiple sclerosis. This results in inappropriate
and involuntary bladder contractions (called neurogenic detrusor overactivity)
often leading to incontinence. These patients develop bladders that cannot hold
as much urine as a healthy person. Futhermore, the pressures within the
bladder are abnormally high and can lead to an increased risk of kidney damage.
Botulinum neurotoxins (such as BOTOX) are known to block the release of
acetylcholine (the chemical signal which triggers the bladder to contract). The
toxin is locally acting and has a transient (temporary) effect. BOTOX injected
into the bladder detrusor muscle has been shown to block the unwanted bladder
contractions and the effect can last for many months after a treatment
Study objective
Objective: The principal objective is to evaluate the safety and efficacy of
two doses of BOTOX (200 Units or 300 Units) compared with placebo injected into
the bladder wall in patients who have urinary incontinence due to neurogenic
detrusor overactivity. These patients will have not been adequately managed
with anticholinergic drug therapy.
Study design
Study design / population
This will be a multicenter, double-blind, randomized, placebo-controlled,
parallel-group study to assess the safety and efficacy of treatments with two
dosages of BOTOX® in patients with neurogenic detrusor overactivity.
Approximately 260 patients will be randomised at approximately 50 sites. The
representative sub-groups of this population are spinal cord injury or multiple
sclerosis patients with urinary incontinence who have not been adequately
managed with anticholinergic therapy. Study randomization will be stratified
to treatment by centre according to overactive bladder etiology (spinal cord
injury or multiple sclerosis) and concurrent anticholinergic therapy at
screening (use or non-use). Patients will be randomized at Day 1 to receive
one of 2 doses of BOTOX® (200 U or 300 U) or placebo in a ratio of 1:1:1.
Enrolment will be managed across all study centres so that approximately 50% of
the patients randomized will be of spinal cord injury etiology and 50% of
multiple sclerosis etiology. Following a minimum of 12 weeks after treatment
1, patients are eligible to receive a second treatment if re-treatment criteria
are met. Patients receiving BOTOX® for the first treatment will continue to be
treated with the same dose received for the first treatment. Patients
receiving placebo for the first treatment will receive either BOTOX® 200 U or
300 U according to a randomization schedule assigned prior to the beginning of
the first treatment. Only one treatment randomization number will be assigned
to each patient prior to the beginning of the first treatment, and will be
associated with one of the following treatment sequences:
Treatment Sequences
1) BOTOX® 200U (treatment 1) / BOTOX® 200 U (treatment 2); 2) BOTOX® 300U
(treatment 1) / BOTOX® 300 U (treatment 2); 3) Placebo (treatment 1) / BOTOX®
200 U (treatment 2); 4) Placebo (treatment 1) / BOTOX® 300 U (treatment 2)
The above treatment sequence will have a ratio of 1:1:0.5:0.5.
All patients will be followed for safety and efficacy for 104 weeks from
Randomization/Day 1 or for 12 weeks following treatment 2, whichever occurs
sooner.
Intervention
The studymedication is injected in the bladder wall through cystoscopy
administered as 30 mL injections each of 1 mL, evenly distributed into the
detrusor, avoiding the trigone and base.

Inclusion criteria
[1] Patient is male or female, aged 18 to 80 years old [2] Patient weighs * 50 kg (110 lb) [3] Written informed consent has been obtained [4] Written Authorization for Use and Release of Health and Research Study Information (US sites only) has been obtained [5] Written Data Protection Consent (European sites only) has been obtained [6] Written documentation has been obtained in accordance with the relevant country and local privacy requirements, where applicable [7] Patient has urinary incontinence as a result of neurogenic detrusor overactivity for a period of at least 3 months prior to screening as a result of spinal cord injury or multiple sclerosis, determined by documented patient history. In addition [7a] Spinal cord injury patients must have a stable neurological injury level at T1 or below (cervical injuries are excluded) occurring * 6 months prior to screening; [7b] Multiple sclerosis patients must be clinically stable in the investigator*s opinion, for * 3 months prior to screening and have an Expanded Disability Status Scale (EDSS) score * 6.5. [8] Patient has detrusor overactivity (defined as a phasic rise in bladder pressure during the filling phase determined by urodynamics) demonstrated during the screening period or Day 1 (prior to randomization) [9] Patient is able to complete study requirements including electronic bladder diary completion and attend all study visits (telephone and clinic), in the opinion of the investigator [10] Patient has not been adequately managed with one or more anticholinergics for their urinary incontinence, in the opinion of the investigator. Not adequately managed is defined as an inadequate response or intolerable side effects after at least one month of anticholinergic therapy on an optimized dose [11] For patients taking anticholinergic medication for their neurogenic overactive bladder, dose is stable and patient is willing to maintain same dosing during study participation [12] Patient has a negative pregnancy result if female and of childbearing potential The following criteria are also required for entry into the study at Randomization/Day 1: [13] Patient experiences * 14 episodes of urinary incontinence per week with no more than 2 incontinent-free days, determined by completion of patient bladder diary during the screening period [14] Patient currently uses or is willing to use clean intermittent catheterization (CIC) to empty the bladder (indwelling catheter is not permitted). Patients currently on CIC should be willing to maintain an established CIC frequency throughout the study. Caregiver may perform CIC [15] Patients with a negative urine culture result must take an antibiotic medication for 3 days immediately prior to Randomization/Day 1 and agree to continue antibiotic medication for at least 3 days following treatment.
